Quartz Glass Tubes: High-Performance Solutions for Industrial and Scientific Applications

Quartz glass tubes, also known as fused silica tubes, are essential components in industries that demand high-temperature resistance, excellent purity, and outstanding optical clarity. In this article, we explore the key properties of quartz glass, different types of quartz tubes, and how to choose the right one for your needs.


1. What Is a Quartz Glass Tube?

A quartz glass tube is a cylindrical component made from high-purity silicon dioxide (SiO₂). Compared to ordinary glass, quartz glass can withstand much higher temperatures and offers excellent resistance to chemicals and UV radiation.

Quartz tubes are widely used in:

  • Semiconductors

  • Laboratory research

  • UV sterilization

  • Industrial heating

  • Optical systems


2. Key Properties of Quartz Glass Tubes

Quartz glass tubes offer a unique combination of thermal, optical, and chemical advantages:

  • High Temperature Resistance: Withstands up to 1100°C for continuous use, and 1450°C for short durations.

  • Optical Clarity: Transmits more than 90% of UV, visible, and infrared light.

  • Chemical Stability: Resistant to most acids and alkalis (except hydrofluoric acid).

  • Low Thermal Expansion: Helps prevent cracking under temperature changes.

  • High Purity: Suitable for semiconductor and scientific-grade applications.


3. Industrial Applications of Quartz Glass and Quartz Tubes

3.1 Semiconductor & Electronic Uses for Quartz Glass Tubes

In semiconductor manufacturing, quartz tubes are essential for processes such as:

  • Wafer diffusion and annealing

  • CVD (Chemical Vapor Deposition)

  • Plasma etching and oxidation chambers

Their high purity prevents contamination, and their heat tolerance supports precise, repeatable cycles.


3.2 Quartz Tubes in Laboratory and Scientific Applications

Quartz glass tubes are ideal for laboratory work involving high temperatures and chemical reactions.

Common uses include:

  • Quartz reactors and crucibles

  • UV-visible spectroscopy cells

  • Thermal and optical test setups


3.3 High-Temperature Quartz Glass Tubes for Industrial Heating

In industrial heating systems, high-temperature quartz tubes are used as:

  • Protective sleeves for heating elements

  • Infrared (IR) heater tubes

  • Gas and fluid transfer conduits in furnaces

Quartz’s resistance to heat shock makes it a safer choice than standard glass or ceramics.


3.4 UV Quartz Tubes for Sterilization and Water Treatment

UV quartz tubes are widely used to protect UV lamps in systems for:

  • Drinking water purification

  • Wastewater disinfection

  • Air and surface sterilization

Their high UV transmittance ensures efficient sterilization and long lamp life.


3.5 Quartz Glass in Optical and Laser Technologies

Quartz glass tubes are used in optics for:

  • Fiber optic transmission

  • Laser beam delivery systems

  • Optical windows and prisms

Quartz’s high clarity and low impurity levels ensure clean, distortion-free light transfer.


4. Types of Quartz Tubes and Their Applications

Each quartz tube type offers specific benefits depending on your application.


5. How to Choose the Right Quartz Glass Tube for Your Needs

Choosing the right quartz glass tube involves several key factors:

5.1 Temperature Resistance

Ensure the tube meets the required thermal conditions. Our tubes can operate at 1100°C continuously and withstand up to 1450°C briefly.

5.2 Purity

For semiconductors and optics, use 99.99% high-purity quartz. Industrial heating may allow for slightly lower grades.

5.3 Dimensions

We offer quartz tubes from 1mm to 1000mm in diameter, with wall thickness from 0.5mm to 10mm.

5.4 Optical Properties

Choose high-transmission quartz for UV work. Use opaque quartz for thermal shielding.

5.5 Chemical Resistance

Quartz resists most chemicals and is suitable for harsh or corrosive environments.

7. FAQs: Quartz Glass Tubes Explained

Q1: What’s the difference between quartz glass and borosilicate glass?
Quartz glass has a higher working temperature (>1200°C vs. 500°C), greater UV transmission, and better purity.

Q2: Can quartz tubes handle sudden temperature changes?
Yes. Quartz has low thermal expansion and good thermal shock resistance. Still, avoid extremely rapid changes.

Q3: How do I clean quartz tubes?
Use deionized water or isopropyl alcohol. Do not use abrasive materials or hydrofluoric acid.

Q4: Can I order custom quartz tubes?
Absolutely. FG Quartz specializes in made-to-order quartz solutions based on your drawings or specs.
